14 Claims.

This invention relates to a gang plow structure. More specifically, it relates to a plow structure so designed that certain of the strains, normally incident to transporting of the plow in raised position, are eliminated.

In gang plow constructions provided with a draw-bar extending forwardly from an intermediate point of the plow beam and a diagonal drawbar connecting the front end of the plow beam and the other draw-bar, it has been found that the axle of the furrow wheel at the front end of the plow beam will frequently break when the plow is being turned in raised position because side thrust is applied to the axle at a point considerably removed from the Wheel rather than as close to the wheel as possible.

Furthermore, in such a construction the forwardly extending draw-bars are normally at tached to one another at a forward point, and another bar extends between the tractor pulling the plow and this forward point of juncture of the draw-bars. Some difficulty has been experienced in the joining of the three members and in the provision of the proper support against strain of the members and the connection.

An object of the present invention is to eliminate the breaking of the axle of the front furrow wheel of a plow when turns are being made.

A further object of the invention is the provision of a plow construction wherein the thrust of turning is applied as near the front furrow wheel as possible.

tractor and the point of juncture of the forwardly extending and diagonal bars of a plow,

Still another object is the provision of a novel arrangement for connecting and supporting a bar connected to the tractor at the point of juncture of the forwardly extending and diagonal drawbars of a plow.

Other objects will appear from the disclosure.

According to the present invention, a plow beam has a first draw-bar extending from an intermediate point and a second draw-bar extending diagonally from the stub axle of the furrow wheel at the front end of the plow beam below the beam to the first draw-bar. There is also another member connected to the axle of the furrow wheel and to the draw-bars, which is adapted to effect a turning of the furrow wheel when the plow is turned. These draw-bars are joined at a forward point, and from this point another member extends to a connection with the tractor.

This member also extends rearwardly from the 2 point of connection to the draw-bars, terminating in a portion of arcuate form extending from ei. ther side of the member. This arcuate portion extends under the draw-bars and serves to support them.

In the drawings:

Figure l is a plan view of a gang plow;

Figure 2 is a section taken along the line 22 of Figure 1;

Figure 3 is a section taken along the line 3--3 of Figure 2; and,

Figure t is a section taken along the line 4 of Figure 3.

As seen in Figure 1, a plow ID has a diagonally extending plow beam H, which carries a plurality of disk plow elements 12. Th rear end of the plow beam has brackets i3 and I4 attached thereto. A land wheel I5 is connected to the bracket l3 by means of an axle IS. A rear furrow wheel I! is connected to the bracket I4 bybracket 3| is attached and carries a front furrow wheel 32, by means of an axle 33, having a first portion 34 extending axially from the wheel 32 and a second portion 35 extending at an angle from the first portion 34 and being journaled in the bracket 3|. A hand-operated lifting mechanism 36 serves to raise the front end of the plow beam with respect to the front furrow wheel 32.

A bent strap member 31 is rigidly welded or secured along one edge at 38 to the portion 35 of the axle 33 immediately above the juncture of the portions 34 and 35. One end of a drawbar 39, formed of adjustable sections of angle iron, is attached to the strap 31 at 40. The other end of the bar 39 is attached to the forward end of the draw-bar 24 at 4 l.

A short channel member 43 having its flanges fixed to the under side of the strap 3'lhas the por.- tion 34 of the axle 33 extending through it and rigidly welded or secured thereto, as at 44, the strap being curved to nest the part of the portion 34. A strap member 45 is attached to the under side of the channel member 43 as Well as to the strap 31, as at 46. At the end of the'strap 31, one end of a member 48, formed of adjustable sections of angle iron, is pivoted. The other end of the member 48 is pivotally attached to a member 49 pivoted in turn on the draw-bars 24 and 39 at their point of attachment at 4|. One end of the member 49 has an arcuate extension 50, which serves to support the draw-bars 24 and 39. The other end of the member 49 is pivoted for lateral pivotal movement at to the U- member 52 attached to a tractor (not shown).

When the plow is to be transported, the plow beam II is raised with respect to the land wheel I5, near furrow wheel l1, and front furrow wheel 32 by means of lifting devices 20, 2!, and 36. If the plow is to be turned to'the right, the tractor is turned to the right, pulling the member 4a to the dotted line position. The member 49 pulls the member 48, strap 31, axle 33, and front furrow wheel 32 around to the dotted line positions.

As the turn is made, the draw-bar 39 exerts a side thrust on the axle 33 through the strap 31. Since the strap 31 is attached to the axle 33 just beyond the axially extending portion 34, the thrust is transmitted relatively close to the furrow wheel 32, and there is Very little likelihood that the axle will break. This is a distinct improvement over the construction in which the drawbar 39 is connected to the bracket 3!. In such a case, the side thrust on the axle 33 in the raised position of the plow is transmitted at a point considerably removed from the wheel, and the likelihood of breaking of the axle is considerable. The channel member 43 and the strap 31 welded to the respective axle portions form means rigidly fitted and secured on the first and second portions of the axle 33.

The plow shown in the drawings has individual lifting mechanisms operable by hand or manually, but it will be apparent that the invention may be applied to plows which have other types of lifting mechanisms, such as power lifts.

The intention is to limit the invention only in the terms of the appended claims.
